from the docs:
Next.js can serve static files, like images, under a folder called
public in the root directory. Files inside public can then be
referenced by your code starting from the base URL (/).
So, first add an image to public/my-image.png
and then you can reference it:
<img src="/my-image.png" />
I think next.js will have a watch on this directory so you won’t need to restart
your server every time you put something in there.
